This paper examines the origin, range and meaning of the Principle of Action and Reaction in Kant’s mechanics. On the received view, it is a version of Newton’s Third Law. I argue that Kant meant his principle as foundation for a Leibnizian mechanics. To find a ‘Newtonian’ law of action and reaction, we must look to Kant’s ‘dynamics,’ or theory of matter. I begin, in part I, by noting marked differences between Newton’s and Kant’s laws of action and reaction. I (...) argue that these are explainable by Kant’s allegiance to a Leibnizian mechanics. I show (in part II) that Leibniz too had a model of action and reaction, at odds with Newton’s. Then I reconstruct how Jakob Hermann and Christian Wolff received Leibniz’s model. I present (in Part III) Kant’s early law of action and reaction for mechanics. I show that he devised it so as to solve extant problems in the Hermann-Wolff account. I reconstruct Kant’s views on ‘mechanical’ action and reaction in the 1780s, and highlight strong continuities with his earlier, pre-Critical stance. I use these continuities, and Kant’s earlier engagement with post-Leibnizians, to explain the un-Newtonian features of his law of action and reaction. (shrink)

This paper examines the young Kant’s claim that all motion is relative, and argues that it is the core of a metaphysical dynamics of impact inspired by Leibniz and Wolff. I start with some background to Kant’s early dynamics, and show that he rejects Newton’s absolute space as a foundation for it. Then I reconstruct the exact meaning of Kant’s relativity, and the model of impact he wants it to support. I detail (in Section II and III) his polemic engagement (...) with Wolffian predecessors, and how he grounds collisions in a priori dynamics. I conclude that, for the young Kant, the philosophical problematic of Newton’s science takes a back seat to an agenda set by the Leibniz-Wolff tradition of rationalist dynamics. This results matters, because Kant’s views on motion survive well into the 1780s. In addition, his doctrine attests to the richness of early modern views of the relativity of motion. (shrink)

Much early modern metaphysics grew with an eye to the new science of its time, but few figures took it as seriously as Emilie du Châtelet. Happily, her oeuvre is now attracting close, renewed attention, and so the time is ripe for looking into her metaphysical foundation for empirical theory. Accordingly, I move here to do just that. I establish two conclusions. First, du Châtelet's basic metaphysics is a robust realism. Idealist strands, while they exist, are confined to non-basic regimes. (...) Second, her substance realism seems internally coherent, so her foundational project appears successful.I have two aims in this paper. Historically, I show that du Châtelet's main source of inspiration was Christian... (shrink)

I uncover here a conflict in Kant’s natural philosophy. His matter theory and laws of mechanics are in tension. Kant’s laws are fit for particles but are too narrow to handle continuous bodies, which his doctrine of matter demands. To fix this defect, Kant ultimately must ground the Torque Law; that is, the impressed torque equals the change in angular momentum. But that grounding requires a premise—the symmetry of the stress tensor—that Kant denies himself. I argue that his problem would (...) not arise if he had kept his early theory of matter as made of mass points, or “physical monads.”. (shrink)

My thesis in this paper is: the modern concept of laws of motion—qua dynamical laws—emerges in 18th-century mechanics. The driving factor for it was the need to extend mechanics beyond the centroid theories of the late-1600s. The enabling result behind it was the rise of differential equations. -/- In consequence, by the mid-1700s we see a deep shift in the form and status of laws of motion. The shift is among the critical inflection points where early modern mechanics turns into (...) classical mechanics as we know it. Previously, laws of motion had been channels for truth and reference into mechanics. By 1750, the laws lose these features. Instead, now they just assert equalities between functions; and serve just to entail (differential) equations of motion for particular mechanical setups. This creates two philosophical problems. First, it’s unclear what counts as evidence for the laws of motion in the Enlightenment. Second, it’s a mystery whether these laws retain any notion of causality. That subverts the early-modern dictum that physics is a science of causes. (shrink)

I examine here if Kant can explain our knowledge of duration by showing that time has metric structure. To do so, I spell out two possible solutions: time’s metric could be intrinsic or extrinsic. I argue that Kant’s resources are too weak to secure an intrinsic, transcendentally-based temporal metrics; but he can supply an extrinsic metric, based in a metaphysical fact about matter. I conclude that Transcendental Idealism is incomplete: it cannot account for the durative aspects of experience—or it can (...) do so only with help from a non-trivial metaphysics of material substance. (shrink)

Early modern foundations for mechanics came in two kinds, nomic and material. I examine here the dynamical laws and pictures of matter given respectively by Newton, Leibniz, and Kant. I argue that they fall short of their foundational task, viz. to represent enough kinematic behavior; or at least to explain it. In effect, for the true foundations of classical mechanics we must look beyond Newton, Leibniz, and Kant.

Much scholarship has claimed the physics of Emilie du Châtelet’s treatise, Institutions de physique, is Newtonian. I argue against that idea. To do so, I distinguish three strands of meaning for the category ‘Newtonian science,’ and I examine her book against them. I conclude that her physics is not Newtonian in any useful or informative sense. To capture what is specific about it, we need better interpretive categories.

Newton rested his theory of mechanics on distinct metaphysical and epistemological foundations. After Leibniz's death in 1716, the Principia ran into sharp philosophical opposition from Christian Wolff and his disciples, who sought to subvert Newton's foundations or replace them with Leibnizian ideas. In what follows, I chronicle some of the Wolffians' reactions to Newton's notion of absolute space, his dynamical laws of motion, and his general theory of gravitation. I also touch on arguments advanced by Newton's Continental followers, such as (...) Leonhard Euler, who made novel attempts to defend his mechanical foundations against the pro-Leibnizian attack. This examination grants us deeper insight into the fate of Newton's mechanics on the Continent during the early eighteenth century and, more specifically, sheds needed light on the conflicts and tensions that characterized the reception of Newton's philosophy of mechanics among the Leibnizians.

I explain and assess here Huygens’ concept of relative motion. I show that it allows him to ground most of the Law of Inertia, and also to explain rotation. Thereby his concept obviates the need for Newton’s absolute space. Thus his account is a powerful foundation for mechanics, though not without some tension.

I argue that the key dynamical concepts and laws of Newton's Principia never gained a solid foothold in Germany before Kant in the 1750s. I explain this absence as due to Leibniz. Thus I make a case for a robust Leibnizian legacy for Enlightenment science, and I solve what Jonathan Israel called “a meaningful historical problem on its own,” viz. the slow and hesitant reception of Newton in pre-Kantian Germany.

Newton had a fivefold argument that true motion must be motion in absolute space, not relative to matter. Like Newton, Kant holds that bodies have true motions. Unlike him, though, Kant takes all motion to be relative to matter, not to space itself. Thus, he must respond to Newton’s argument above. I reconstruct here Kant’s answer in detail. I prove that Kant addresses just one part of Newton’s case, namely, his “argument from the effects” of rotation. And, to show that (...) rotation is relative to matter, Kant changes the meaning of ‘relative motion.’ However, that change puts Kant’s doctrine in deep tension with Newton’s science. Based on my construal, I correct earlier readings of Kant by John Earman and Martin Carrier. And, I argue that we need to revise Michael Friedman’s influential view of Kant. Kant’s struggle, I conclude, illustrate the difficulties that early modern relationists faced as they turned down Newtonian absolute space ; and it typifies their selective engagement with Newton’s case for it. (shrink)

I examine here if Kant’s metaphysics of matter can support any late-modern versions of classical mechanics. I argue that in principle it can, by two different routes. I assess the interpretive costs of each approach, and recommend the most promising strategy: a mass-point approach.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Newton's Metaphysics: Essays by Eric SchliesserMarius StanEric Schliesser. Newton's Metaphysics: Essays. Oxford: Oxford University Press, 2021. Pp. 328. Hardback, $99.90.Newton owes his high regard to the quantitative science he left us, but his overall picture of the world had some robustly metaphysical threads woven in as well. Posthumous judgment about the value of these threads has varied wildly. Christian Wolff thought him a metaphysical rustic, as did Hans (...) Reichenbach some two centuries later ("Die Bewegungslehre bei Newton, Leibniz und Huygens," Kant-Studien 29 [1924]: 416–38). In the 1960s, the tide would turn, as Howard Stein and James Edward McGuire separately began to show that Newton's metaphysics was not just sophisticated, but often more compelling than its early modern alternatives (see respectively "Newtonian Spacetime," Texas Quarterly 10 [1967]: 174–200; and Tradition and Innovation: Newton's Metaphysics of Nature [Dordrecht: Kluwer Academic Publishers, 1995]). Eric Schliesser's book unfolds in that same register of appreciative, high scholarship, and it attests to the enduring attraction of its subject.The book grew out of previous discrete papers, to which he added a few more for this occasion. Accordingly, it does not come with a master argument. Rather, it is an in-depth exploration of some key metaphysical themes in Newton. As such, it befits its subject figure, who reflected on themes and concepts while stopping short of working out systems.The first major theme is Newton and Spinozism. The latter does not denote Spinoza's metaphysics. In fact, Schliesser explains, Newton shared with Spinoza some weighty commitments, for example, to space being actually infinite, and to substance monism: "for Newton, there is strictly speaking only one genuine substance," namely, God (33). Rather, "Spinozism" is an interpreter's category for a bundle of three theses: identifying God and nature; denying final causation in the physical world; and the assumption of "blind" metaphysical necessity. Some counted Hobbes and John Toland as Spinozist in this sense, and even Epicurus, avant la lettre. Newton and his followers argued vehemently against this package, as Schliesser shows in chapters 4, 5, and 8. Their chief complaint was that Spinozism is unable to account for the "origin of motion," for a certain type of order, and for the stability of cosmological structure—and to do so in a way that "meets the standards of Newtonian mechanics" (122). This interpretive lens allows Schliesser to draw Kant in, by reading his youthful Theory of Heaven as a possible Spinozist reply to their objections (chapter 3). [End Page 157]A second theme is the metaphysics of mechanics, where Schliesser weaves together several strands. One is the ontology of gravity, for which he offers a novel construal: for Newton, gravity counts as real, but in a qualified sense. Namely, it is not essential and not intrinsic: "even after creation, a lonely partless particle of matter in the universe would not be said to gravitate." And gravity is relational: a "shared quality" of two or more bits of matter, which obtains in virtue of their sharing a nature (19). Another strand is Newton's ontology of time—really, a subtle, difficult topic long neglected. Famously, Newton in Principia defends absolute, true, and mathematical time. The question is what these three qualifiers denote, and whether Newton thought they were synonymous. Schliesser in chapter 7 argues for the provocative view that "absolute" and "true" time are not identical concepts; rather, they pick out different entities. These entities share a common structure, namely, metric and topological. That makes them species of "mathematical" time (179). But, Schliesser contends, Newton has unequal warrant for his two concepts of time.Yet another theme is formal causation. It comes to the fore in chapter 5, which grapples with Newton's opaque idea that space is an "emanative effect." Schliesser explains that here, "emanation picks out a species of formal causation" (147), but in a novel, early modern sense that comes from Bacon, not Aristotle. If space has a formal cause, then so has its twin brother, time, the topic of chapter 7. God is their common formal cause. Then in chapter 6 (coauthored with Zvi Biener) Schliesser adds that, for Newton, laws... (shrink)

This chapter looks at Euler’s relation to Newton, and at his role in the rise of ‘Newtonian’ mechanics. It aims to give a sense of Newton’s complicated legacy for Enlightenment science, and to raise awareness that some key ‘Newtonian’ results really come from Euler.

Modern philosophy of physics debates whether motion is absolute or relative. The debate began in the 1600s, so it deserves a close look here. Primarily, it was a controversy in metaphysics, but it had epistemic aspects too. I begin with the former, and then touch upon the latter at the end.

On an influential view, Newton's mechanics is built into Kant's very theory of exact knowledge. However, Newtonian dynamics had serious explanatory limits already known by 1750. Thus, we might worry that Kant's Analytic is too narrow to ground enough exact knowledge. In this paper, I draw on Enlightenment dynamics to show that Kant's notion of determinate objecthood is sufficiently broad, non-trivial, and still relevant to the present.

I emphasize two merits of Eric Watkins’ account in "Kant on Laws": the strong evidential support it has, and the central place it gives to Kant’s laws of mechanics. Then, I raise two questions for further research. 1. What kind of evidential reasoning confirms a Kantian law? 2. Do natures explain Kantian laws? If so, how?

Leibniz is committed to a form of cosmic eternity, on account of his natural theology and foundations for dynamics. However, his views on perpetuum mobiles entail that a particularly attractive type of cosmic eternity is out of reach for Leibniz.

In his Metaphysical Foundations of Natural Science, Kant presents the “pure part” of natural science – that is, the a priori principles holding of matter. This special metaphysics of matter is, Kant claims, grounded on the general metaphysics of nature described in the System of Principles of his first Critique. This chapter develops a comprehensive account of Kant’s framework for natural science that touches on interpretive issues that arise in the transition from general to special metaphysics and that outlines his (...) dynamics and its limitations.

This is a book with a purpose: it aims to chronicle the life of a concept from its birth in ancient Greece to its growth into centrality for early modern metaphysics, and its end with Kant, after whom classical space got displaced to a marginal position.

Dealing with the continuously increasing rates of families wanting to either significantly delay or completely postpone their infant's vaccines has created an alarmingly untenable dilemma for the general pediatricians dealing with these families on a daily basis. Pediatricians must decide whether to continue to provide substandard care by foregoing many or most of the infant's highly recommended protective vaccines, or whether to dismiss from the practice the family who refuses vaccines. Much has been written about why they should retain these (...) families, but this paper will discuss some reasonable rationales as to why nearly 40% of pediatricians choose dismissal of these families.

Note: Paper to appear in special issue of the journal Psychology of Consciousness: Theory, Research, and Practice, on the evolution of consciousness //// Klein, Nguyen, & Zhang (in press) argued that the evolutionary transition from respondent to agent during the Cambrian Explosion would be a promising vantage point from which to gain insight into the evolution of organic sentience. They focused on how increased competition for resources -- in consequence of the proliferation of new, neurally sophisticated life-forms -- made awareness (...) of the external world (in the service of agentic acts) an adaptive priority. The explanatory scope of Klein et al (in press) was limited to consideration of the conscious apprehension of externally sourced content – i.e., content delivered from the sensory registration of objects occupying phenomenal space. But consciousness – at least for humans -- takes its objects from internal as well as external sources. In the present article we extend their analysis to the question of how internally sourced content (i.e., mental states) became the object of conscious apprehension. (shrink)

Most music we hear comes to us via a recording medium on which sound has been stored. Such remoteness of music heard from music made has become so commonplace it is rarely considered. _Musical Performance: A Philosophical Study_ considers the implications of this separation for live musical performance and music-making. Rather than examining the composition or perception of music as most philosophical accounts of music do, Stan Godlovitch takes up the problem of how the tradition of active music playing (...) and performing has been challenged by technology and what problems this poses for philosophical aesthetics. Where does does the value of musical performance lie? Is human performance of music a mere transfer medium? Is the performance of music more expressive than recorded music? Musical Performance poses questions such as these to develop a fascinating account of music today. musicians - but via some recording medium on which sound has been stored. (shrink)

Craig Callender, Jonathan Cohen and Markus Schrenk have recently argued for an amended version of the best system account of laws – the better best system account (BBSA). This account of lawhood is supposed to account for laws in the special sciences, among other desiderata. Unlike David Lewis's original best system account of laws, the BBSA does not rely on a privileged class of natural predicates, in terms of which the best system is formulated. According to the BBSA, a contingently (...) true generalization is a law of a special science S iff the generalization is an axiom (or a theorem) of the best system relative to the set of predicates used by special science S. We argue that the BBSA is, at best, an incomplete theory of special science laws, as it does not account for typical features of special science laws, such as attached ceteris paribus conditions and the idealized character of law statements in these disciplines.

I argue that the feeling that one is the owner of his or her mental states is not an intrinsic property of those states. Rather, it consists in a contingent relation between consciousness and its intentional objects. As such, there are (a variety of) circumstances, varying in their interpretive clarity, in which this relation can come undone. When this happens, the content of consciousness still is apprehended, but the feeling that the content “belongs to me” no longer is secured. I (...) discuss the implications of a mechanism enabling personal ownership for understanding a variety of clinical syndromes as well normal mental function. (shrink)

This paper brings about a conversation between Schumpeterian and Polanyian perspectives on markets and their central role in the capitalist economy. For Schumpeter, markets were critical to the process of selftransformation of economic activity, but in his vision, markets as such were largely taken for granted. Markets enabled the introduction of new processes and products equally as well as rendering economic activities obsolete, with the entrepreneur and firm as agents of change, generating new combinations of activities and driven by the (...) creative power of knowledge. Innovation and markets are jointly the engines of endogenous growth. For Karl Polanyi, by contrast, although markets were the central feature of the capitalist economy from the beginning of the nineteenth century, his main interest is the constant impulse for markets as institutions to expand into every aspect of social life and the countermovement of regulation to restrain what he sees as their essentially destructive nature. His focus is therefore on markets as instituted economic processes, driven by the double movement of regulation and de-regulation. He scarcely considers innovation in production or consumption, concentrating on institutions of exchange and distribution. The paper explores the two perspectives in order to ask the question that their confrontation raises: What is the relation between intra-market endogenous change and marketframework institutional change? To test out each perspective, a schematic “long-duration” empirical account of the United Kingdom food distribution markets is subjected to a Schumpeterian and Polanyian reading, and each is exposed for complementary deficits. A broader explanatory framework is sketched that proposes analysis of innovation in market institutions--especially processes exchange and distribution-- in combination with innovation in production and consumption. It is suggested that to explore the constant change of capitalist economies, these four economic domains each involve different orders of innovation and transformation that have complex feedbacks and interactions with each other. Rather than according primacy to one or other order of change, we require a complex causal account embracing multiple instituted economic processes.Cet article discute de la vision des marchés et de leur rôle central dans l’économie capitaliste selon Schumpeter et Polanyi. Pour Schumpeter, les marchés sont essentiels au processus d’auto transformation de l’activité économique, mais dans son approche il présuppose l’existence des marchés. Les marchés permettent l’introduction de nouveaux processus et produits et rendent en même temps les activités économiques obsolètes. Les marchés, avec l’entrepreneur et la firme comme agents du changement, créent de nouvelles combinaisons d’activités et sont dynamisés par le pouvoir créatif de la connaissance. L’innovation et les marchés sont conjointement les moteurs de la croissance endogène. Chez Karl Polanyi, en revanche, bien que les marchés soient un élément central de l’économie capitaliste dès le début du 19ème siècle, l’attention se porte sur le mouvement permament des marchés-institutions à s’étendre à tous les domaines de la vie sociale ainsi que sur le contre-mouvement de la régulation à limiter ce que Polanyi considère comme la nature destructrice des marchés. Son interêt se porte ainsi aux marchés comme des processus économiques établis, conduits par un double mouvement de régulation et de dérégulation. Il ne considère que rarement l’innovation de production ou de consommation, et se concentre sur les institutions de l’échange et de la distribution.L’article explore les deux visions afin de sinterroger sur ce que la confrontation des approches soulève comme question: Quelle est la relation entre les changements endogènes intra marché et les changements institutionnels de la structure de marché? Pour tester chacune des visions, un compte-rendu empirique sur longue période de la distribution alimentaire au Royaume-Uni est soumis à une lecture Schumpeterienne et Polanyienne.Un cadre explicatif plus large est esquissé et suggère une analyse de l’innovation des institutions de marché - particulièrement des processus d’échange et de distribution - conjointement à l’innovation de production et de consommation. Il est suggéré que pour analyser le changement permanent des économies capitalistes, il faut considérer les ordres d’innovation et de transformation de ces quatres domaines économiques qui connaissent des “effets de retour” ainsi des interactions. Au lieu d’accorder la primauté à un des ordres de changement, il est nécessaire de rendre compte d’une causalité complexe qui prend en compte des processus économiques multiples. (shrink)
